I think I know why this is happening to you guys. When I played, I clicked on the "expert" (four suit) version. acumark may have chosen the "regular" (two suit) mode, and # notes he/she chose the "casual" (one suit) version.

Stan, I don't know how you have time to waste on anything! With all the hobbies you seem to have and keeping up with this blog (including the reading you must do to find material for this blog), I'm impressed you have any time to play something like Solitaire. :) More power to you!

There are Choose(52, 10) = 52!/(10! 42!) ways of choosing 10 black cards from among the 52 black cards in 2 decks, and Choose(104, 10) = 104!/(10! 94!) ways of choosing 10 cards from among all of the cards in the two decks. The probability of the 10 showing cards being all black is the ratio of these two quantities, which works out to 0.0006061083 -- pretty close to your guess of 1/1650 = 0.0006060606

I have to echo Timothy's comment! How could you possibly have enough time to play a computer-based ANY game, or any game of any sort, at all? You do no housework? Sleep only 2 hours a night? Vitamise all food with a blender and drink meals with a straw to save time? What's the trick?

"Tai-wiki-widbee" is an eclectic mix of trivialities, ephemera, curiosities, and exotica with a smattering of current events, social commentary, science, history, English language and literature, videos, and humor. We try to be the cyberequivalent of a Victorian cabinet of curiosities.
